EMC och Artificiell Intelligens

Artificiell Intelligens (AI) är ett samlingsbegrepp inom vetenskap och teknikutveckling där man försöker göra maskiner lika intelligenta som människor. Området har de senaste åren blivit mycket hett och stora möjligheter förutspås inom framtida produkter med AI-tillämpningar. Det är intressant att fundera på vad AI-applikationer kan leda till för EMC-utmaningar.

Troubleshooting EMI (Part II, Susceptibility Problems)

Some simple hints . for identifying and fixing EMI troubles. This second part of our EMI Troubleshooting guidelines is devoted to investigation and cure of EMI susceptibility problems. Since, according to our former article (Ref.1) conducted tests are faster and easier to perform, we will concentrate on these and avoid more complex and expensive radiated susceptibility test set-ups. The first half of this article will address the situation where the equipment at stake is still in the plant or lab, at the end of its development phase or in an early stage of production. The second half will cover the more difficult cases where the faultly equipment is already in service, installed at some customer site.

Using PoE networks to power IoT smart infrastructure for commercial buildings

Communications networks using Power over Ethernet (PoE) technology can now deliver electrical power, as well as transmit communications signals, over standard low-voltage Ethernet cabling to various endpoints, including LED lighting, HVAC controls, cameras and other networked devices, in new or existing commercial buildings. Giovanni Frezza, Group Product Manager for Network Connected Solutions at Molex, reviews PoE technology and standards, discussing how it can power smart lighting and building automation systems, and the benefits these can deliver for building operators and occupants.

Ögat på: EMC från bricka till bricka, del 22

DEL 5: Diverse metoder för EMC-tätning . (Fortsättning). EMC måste tas om hand i alla delar, såväl på elektrisk som på mekanisk systemnivå, och på alla nivåer i en utrustning på ett systematisk och planerat sätt. Denna gång tittar på bl annat skärmning medelst vågledardämning.

Paretoprincipen och EMC

Paretoprincipen . är en empirisk regel enligt vilken 20 procent av orsakerna står för 80 procent av verkan. Principen kallas ibland även 80/20-regeln. Regeln kommer från Vilfredo Pareto (1848-1923) som visade att ca 20 procent av den italienska befolkningen innehade ca 80 procent av egendomen. Denna observation har av andra senare generaliserats och tillämpats inom en rad andra områden och även om de faktiska siffrorna inte alltid råkar bli exakt 80/20 så talar man ändå om principen som sådan för att illustrera att en minoritet av orsaker står för en majoritet av verkan i någon mening.

The Ten Commandments for EMC, part 6

One of the most important . measures to achieve good EMC characteristics is to bond all metallic (conducting) structures together with many wide connections. Connect metal to metal by as large area as possible, with good surface conductivity. These joined parts form a conductive equipotential structure, that act as a reference plane or ground for all electrical and electronic circuit in its vicinity. In practice, the apparatus body and the metal casing, forms this reference plane. In most cases, the ground planes in PCBs must also be connected to the reference plane to achieve the desired EMC properties.

Internet of Things: an IT Security Nightmare

Offprint from strategic outlook 7 . .Internet of Things (IoT) is the collective name given to products that contain electronics that have some form of connection to other systems, usually via the Internet. The number of cyberattacks involving IoT devices has increased in recent years. This, combined with a deteriorating security situation, presents a looming risk of major and wider cyberattacks in which IoT devices will be central. Sweden’s national security and system of total defence are built to a great extent on the resilience of critical societal functions. Many of these have Internet-connected systems that are partially based on IoT products, making them vulnerable to cyberattacks. These systems are clear targets for antagonists. To reduce the risk of serious cyberattacks capable of disrupting critical societal functions, Sweden should have a clear strategy on cybersecurity. Sweden should also take an active role in efforts to increase cybersecurity in commercial IoT products.

A survey of the existence of GPS interference in Europe

Introduction .  The European Union (EU) Horizon2020 project Standardisation of Global Navigation Satellite System (GNSS) Threat Reporting and Receiver Testing through International Knowledge Exchange, Experimentation and Exploitation (STRIKE3) is a new European initiative to support the increasing use of GNSS within safety, security, governmental and regulated applications. One of the objectives of STRIKE3 is the deployment and operation of an international GNSS interference monitoring network to capture the scale and dynamics of the problem, and to work with international GNSS partners to develop, negotiate, promote and implement standards for threat reporting and receiver testing. Both standards are missing across all civil application domains and are considered a barrier to the wider adoption and success of GNSS in the higher value markets.
